DRAlN -TIL' E-LAYING MACHINE.

SPECIFICATION forming part of Letters Patent No. 305,363, datedSeptember 16, 18847 Applicationfiled June 20, 1884. (No model.) I

'To all whom it may concern:

Be it known that I, IvonY Wnnsrnn, of West Liberty, in the county ofMuscatine and State'ofIowa, have invented a new and use ful Improvementin Drain- Tile-Laying Machines,which improvement is fully set forth inthe following specification and accompanying drawings, in which Figure 1is a perspective view. of my improved-drain-tile-laying machine. Fig. 2is a transverse vertical section through X, and Fig. 3 a longitudinalcentral section showing the chute.

In the tile-laying machines in general use the chief obj ections lie inthe fact that the depth of laying cannot be properly gaged, and also thetile, after being laid or placed within the trench, is not sufficientlycovered with soil, whichnecessitates considerable labor to place theland in a condition for farming purposes.

My device consists of beams formed of two parallel pieces, havingbetween them at the forward end avertical post operated vertically bymeans of a rack and bar, and having at the lower end a guiding-shoe forguiding the depth of the device. Rearwardly, a colter provided at thelower end with a hinged shoe has also at the upper end a rack and bar,and rearwardly beneath the beam a peculiarlyshaped mold-board, providedinwardly with, a chute to convey the tile. Externally the mold-board isprovided on each side with one or more inclined planes or ways forelevating the earth within thetrench, depositing the tile beneath, andpermitting the earth to again resume its original position. Suitablehinged guards are provided to aid in conveying the earth rearwardly.Beneath the mold-board is placed a roller which forms a cove to receivethe tile. By means of suitable rods extending rearwardly I provide apair'of guides to assist in placing over the tile such a part of thesoil as may be thrown outwardly from-.the trench by the machine, all ofwhich will now be fully set forth in detail. 7

In the accompanying drawings, Aare a pair of parallel beams set on edgeand at a little distance apart, and ofsuitablelength. These are securedtogether by means of bolts and connecting-pieces A. Between these beams,near the rear end, Iprovide a pair of posts, B and B, a short distanceapart, and secured in position by means of suitable, bolts. At theforward end and between the saidbeams A a vertical post, 0, is providedbetween the eonneeting-pieces A, its rearward side being provided with arack and pinion, G,-having laterally a crank or other device foroperating the vertical post. A pawl, G, is provided to engage with therack-pinion C. At the lower end of this said post 0, I provide atransverse beam, D, to which is secured onthe lower sidelongitu'dinalpieces D, connected together at their front and rear endstolact as a shoe and gage, and which moves alongover the surface of theground. To facilitate the operation of this rectangular. shoe I provideslots in the slidepiece D to receive the bolts at the ends of the beamD,whieh permits it to move freely along the surface of the ground andpass over any uneven place. The lower end of the post B inclines forwardsomewhat, and has on its- I front sidea suitable metallic share, Z), andextending thence rearwardly on each side of this post B, at the sides ofthe posts B, and connecting some distance rearwardly, are placedmold-boards F,dian1ond-shaped in horizontal cross-section, ofanysuitable material. The lower part of each of these mold-boards 1* hasan enlarged part laterally, the upper side forming an inclined. plane,G, upwardly from the forward end near the center of moldboard F, andthen inclines downwardly to the rear. At the forward end of thisinclined plane a shoe, H, is hinged, its forward end forming a broadcutting-point. The upper surface centrally has a share, J, hingedthereto. The upper end of the share passes between the beams A, and isprovided with a rack and pinion, J, with a pawl and suitable crank orother device for operating attached thereto. A share, J, is secured onthe share I by means of a link and made adjustable to any height tofacilitate the cutting of the soil. The bolt K, by means of which theshoe H is hinged to the inclined plane G, has also secured at the endsupright pieces or cutters L, and the upper ends of said cutters inclinelaterally somewhat, and also rearwardly at about the same angle as theshare E, and are secured in position by means of the bracketsL,extending outwardly from the beams A.

I Laterally from the lower side of the rear end of the beams A wings Mextend, curving downwardly at N a short distance therefrom, andconnected at their lower ends to the side of the highest point of theinclined plane G. These are designed to be formed of metal, preferably,and in the same plane and at the same angle laterally as the cutters L.Just within the cutters L and N, I provide one or more suitable pairs ofguides, 0, the upper side turned inwardly, forming a flange inconformity with the inclined plane G. The forward ends of these guides 0have rods P secured thereto, which rods extend upwardly and rearwardly,and are hinged at the upper end of the wing M. Thispermits the guides Oto move along at the surface of the ground, for the purpose of retainingthe core of earth at the side of the machine.

Immediately in the rear of the post B is a chute, Q, extending down andrearwardly and terminating at the lower and rear part of the machinebetween the inclined planes in a shoe, Q. The upper part of the chute ishemispherical in form, and has hinged at its upper end, immediatelyinthe rear of the said chute, a curved arm, R, also hemispherical in crosssection. The two hemispherical curved pieces together form the chutedesigned to receive the tile as the machine moves along. Immediatelyforward of the lower end of this chute a roller, S, is journaled in thebeam of the machine. The periphery of this roller is de signed to becurved in cross-section, and to extend somewhat below the bottom of thema chine, so as to form a cove in the bottom of the trench. I

To the upper end of the cutters N, I connect a pair of rods, T,extending rearwardly and having attached thereto a pair of wedgeshapedpieces, U, having on their inner sides metallic pieces U. The lower partof these metallic pieces extends inward horizontally, while the otherpart extends up nearly at right angles, and is secured to the inner sideof the wedge-shaped pieces. Near the forward end of these pieces atransverse rod, V, is secured and at their rear end a shorter rod, V, isprovided. These pieces slide along on the top of the ground, and serveto throw inwardly all loose dirt which may be thrown out by the machine.A clevis or link, IV, is placed around the post B immediately beneaththe beams A, to the forward ends of which are secured the ends of thepair of rods W, passing forward on either side of the post 0 a-shortdistance beyond, where they unite and have attached thereto a hook orclevis, to which animals or other means or propulsion may be secured.

The operation of this device is as follows: The gageshoe at the forwardend of the machine attached to the post 0 is raised to such a heightfrom the ground as it is designed to lay the tile, by means of a pawl,rack, bar, and pinion C, and secured by means of a rack and pinionconnecting to the share I and shoe H. As the machine moves forward, the

dirt is sliced into two cores, one-half of which passes on each side ofthe moldboard F. At the same time the inclined planes G elevate:the-cOre from the trench and permit the introduction of the tilethrough the opening of the chute. As thesoil passes at its rear part, itrests above the tile. The guides O serve to keep the cores from turningout laterally, while the loss of the dirt that might be incidentallythrown out laterally by the machine is thrown inwardly immediately overthe cores. As will be noticed, the tile may be laid at any depth byelevating the post 0 or the share and shoe H.

What I claim is 1. In a drain-tile machine, a shoe hinged rearwardly,its forward end forming a broad cutting-point, and having on its uppersurface centrally an upwardly-inclined share hinged thereto, and anadjustable share having its forward face concave placed thereon, theupper end provided with a rack, pinion, pawl, and

suitable crank device for operating, substan tially as herein set forth.

2. In a drain tile machine, the metallic share extending rearwardly oneach side of the post and connected at the same distance rearwardly,forming mold-boards diamondshaped in horizontal cross-section, andhaving an inclined base, substantially as herein set forth.

3. Ina drain-tile machine, a pair of guides, O, placed inwardly from thelaterally-inclined cutters, the upper side turned inwardly, forming aflange, the forward end having a rearwardly-inclined rod secured at theupper wing, substantially as and for the purposes herein set forth.

4. The combination of the parallel beams having a pawl, fpinion, andcrank device, with ashare or cutter, E, having thereon an adjustablecutter, J, as shown, and having at the lower end a hinged shoe, H,substantially as herein set forth.

5. The combination of the parallel beams, the laterally-extendingbrackets, and inclined cutters, with diamond-shaped mold-boards andinclined plane G, substantially as described.

6. Thecombination of the parallel beams, the diamond-shaped moldboards,the wings, and inclined cutters, with the horizontallyprojecting rods,having attached thereto a pair of wedgeshaped pieces having ametallicbase flaring inwardly, connected at their forward ends bya rod, andrearwardly by asomewhat shorter rod, substantially as herein set forth.

7. The combination of the diamond-shaped mold-boards with the uprightposts, and the parallel beams with a roller beneath the base of themold-board, substantially as herein set forth.

8. The combination of the diamond-shaped 'mold-'boards with theuprightposts, the parallel beams, and the roller beneath the base, withthe chute between the mold-boards curved downwardly and rearwardly,substantially as herein set forth.

9. The combination of the parallel beams having at the forward end thegage device and rearwardly the hinged shoe and cutter, thelateraHy-inclined cutter, the chute, the moldboards having the inclinedbase, the guidepieces hinged at their forward ends, and the cove-roller,the whole combined and arranged as and for the purposes as herein setforth.

10. The combination, in a drain-tile-laying machine, of the beams A, theupright share or cutter having on either side outwardly inclinedcutters, and the mold-board having the double-inclined planes G,substantially as described.

ll. The combination, with a drain-tile machine, of the attachments U U,having the wedge-shaped pieces with inwardly-extending bases, theforward end connected by means 20 of a rod, and rearwardly by a shorterrod, as described.
